About
This is a Weekly Meta Report for Europe. All data collected are from games played in the last 7 days by high elo players on the European shard.
The report is split into different sections:
- I. Data Collected: infos about the data used in the current report. As you'll probably notice, the sample size is quite small; this is due to limitations with Riot API and should always be taken into account when looking at the data (especially for matchup charts, where the small number of games for specific matchups will lead to unreliable numbers).
- II. Regions Report: analysis on the meta split by region.
- III. Champions Report: analysis on the meta split by champion.
- IV. Cards Report: analysis on the meta split by cards.
Next to almost every chart in this report, there is a "Full data" button; press it to see all the data collected, and check for specific combinations of regions / champions that are not shown in the charts (filtering with the "search" box next to the table).

Meta Report
I. Data collected
Data used in this report are collected from ranked matches of Master players and players that faced master players in ranked.
All games are from the EU shard.
This report analyzes games played by 1043 different players, of which 693 are currently in Master (66.4%).
In total, 5809 matches are collected, played between June 7 and June 13.
Of those matches:
- 4916 are played between 2 Master players (84.6%);
- 891 are played between one Master player and a player below Master (15.3%);
- 2 are played between 2 players below Master (0.0%).
II. Regions Report
Region Playrate
Chart
This chart shows the percentage of decks running a specific region.
The sum of all Regions’ Playrate should be close to 200% since almost every deck runs 2 regions.

III. Champions Report
Champion Playrate
This chart shows the percentage of decks running a specific champion.
The sum of all Champions’ Playrate can be anything between 0% (if every deck is a champion-less deck) and 600% (if every deck is a 6-champions deck). Realistically, the real value will be ~200% since most decks run only 2 champions.

Champion Matchups
Only the 10 Champion Combinations with the highest playrates are shown.
The value shown in each cell is the winrate that the Champion Combination in the row has when playing against the Champion Combination in the column.
To check for matchups that are not in this table, use the tab “Full data” and filter for the desired Champion Combination (sample sizes might be small).

Power Rankings
This chart shows the power rankings for the 20 most played champion combinations.
“Power ranking” is defined in the “Vicious Syndicate way”; explanation taken from their website:
Q: What is the meaning of the Power Rankings and how do you compute Power Ranking scores?
The Power Ranking scores are each deck’s weighted win rate against the field. We calculate a deck’s Power Ranking score by weighting its matchups against other archetypes, factoring each archetype’s frequency.
This means that the Power ranking of a deck is not their observed winrate, but the winrate they should have according to their matchups winrate and the observed frequency of other region combinations.
NB: if in the data collected there are no games between 2 specific champion combinations, I use 50% winrate as a default value in these calculations. Since here I am filtering the most played combinations, this should never happen; but just in case, I’m adding this as a disclaimer. Due to the small sample size, using Bayesian Averages might be a better option. I’ll think about it. In the meantime, I’m blaming Riot for the ridiculously low API rate limit.

Deck Codes
Here are collected the 3 most played deck codes for each of the 20 most frequent champion combinations:
Power Score
This chart shows the position in the meta for the 20 most played champ combinations, in terms of Winrate and Playrate. This one is also an exact copy of Vicious Sindycate’s Power Score chart. From the FAQs on their website:
Q: What is the meaning of the Meta Score and how do you compute it?
The Meta Score is a supplementary metric that measures each archetype’s relative standing in the meta, based on both win rate and prevalence, and in comparison to the theoretical “best deck”.
We take the highest win rate recorded by a current archetype in a specific rank group, and set it to a fixed value of 100. We then determine the fixed value of 0 by deducting the highest win rate from 100%. For example, if the highest win rate recorded is 53%, a win rate of 47% will be set as the fixed value of 0. This is a deck’s Power Score. The range of 47% – 53%, whose power score ranges from 0 to 100, will contain “viable” decks. The length of this range will vary depending on the current state of the meta. Needless to say, it is possible for a deck to have a negative power score, but it can never have a power score that exceeds 100.
We take the highest frequency recorded by a current archetype in a specific rank group, and set it to a fixed value of 100. The fixed value of 0 will then always be 0% popularity. This is a deck’s Frequency Score. A deck’s frequency score cannot be a negative number.
We calculate the simple average of a deck’s Power Score and Frequency Score to find its vS Meta Score. The vS Meta Score is a deck’s relative distance to the hypothetical strongest deck in the game. Think of Power Score and Frequency Score as the coordinates (x, y) of a deck within a Scatter Plot. The Meta Score represents its relative placement in the plane between the fixed values of (0, 0) and (100,100).
If a deck records both the highest popularity and the highest win rate, its Meta Score will be 100. It will be, undoubtedly, the best deck in the game.
IV. Cards Report
Cards Inclusion Rate
Only the 10 Cards with the highest inclusion rate in their respective region are shown.
The value shown for each card is the percentage of decks that include at least one copy of that specific card when playing the region the card belongs to.
To check for specific cards that are not in this chart, or for the most included cards in every region, use the tab “Full data” and filter for the desired Region using the “search” box.

Cards Frequency Wordcloud
This chart shows the most frequently played cards; font size scales with the number of decks playing at least one copy of the card (i.e. the bigger the name of a card is, the higher the number of decks playing that card).
There are probably better ways to visualize this information, but I find wordclouds really cool. I’ll probably add more standard charts abut this topic, maybe…
